serial: mxs-auart: add the DMA support for mx28

2012-11-16T12:42:46+00:00

Only we meet the following conditions, we can enable the DMA support for
auart:

  (1) We enable the DMA support in the dts file, such as
      arch/arm/boot/dts/imx28.dtsi.

  (2) We enable the hardware flow control.

  (3) We use the mx28, not the mx23. Due to hardware bug(see errata: 2836),
      we can not add the DMA support to mx23.

Bindings for gpio, interrupt controller, power management controller,
timer, realtime clock, serial uart, ehci and uhci controllers and
framebuffer controllers used on the arch-vt8500 platform.

Framebuffer binding also specifies a 'display' node which is required
for determining the lcd panel data.

Merge tty-next into 3.6-rc1

2012-08-06T16:48:31+00:00

This handles the merge issue in:
	arch/um/drivers/line.c
	arch/um/drivers/line.h
And resolves the duplicate patches that were in both trees do to the
tty-next branch not getting merged into 3.6-rc1.

Pull TTY/Serial patches from Greg Kroah-Hartman:
 "Here's the "tiny" set of patches for 3.6-rc1 for the tty layer and
  serial drivers.  They were cherry-picked from the tty-next branch of
  the tty git tree, as they are small and "obvious" fixes.  The larger
  changes, as mentioned before, will be saved for the 3.7-rc1 merge
  window.

  All of these changes have been in the linux-next releases for quite a
  while.

This patch adds a "compatible" string for the new 8250 UART type PORT_LPC3220.
This is necessary for initializing LPC32xx UARTs via DT.

tty: of_serial: add no-loopback-test property

2012-07-17T16:16:39+00:00

The loopback test mode is not implemented in all
NS16550 compatible UARTs. The 8250 driver uses the
UPF_SKIP_TEST flag to indicate this, however it is
not possible to set this flag via device-tree.

Add a new 'no-loopback-test' property, and modify
the of_serial driver to set the UPF_SKIP_TEST flag
if the property is present.

serial: Add driver for LPC32xx High Speed UARTs

2012-06-12T22:48:01+00:00

This patch adds a driver for the 3 High Speed UARTs of the LPC32xx SoC that
support up to 921600bps. These UARTs are different from the 4 "Standard" UARTs
of the LPC32xx.
